Dump valve release
At Cydive we have a lot of the Beuchat Masterlift Adventure BCD,s in our rental equipment . Many times the shoulder dump or kidney dump have failed to seal and allowed the air to escape . After pulling on the dump cord a few times they have re-sealed , but this should not be happening in the first place . Please can you advise of what to do next . This has been happening on about 20 of our BCD,s out of 35 .
